Abstract
A measurement system and method of manufacture can include: a pressure resistant structure; a pressure inducer coupled to the pressure resistant structure, the pressure inducer having an engaged configuration, the engaged configuration of the pressure inducer increasing pressure exerted on a portion of a user in contact with the pressure resistant structure; a light source coupled to the pressure resistant structure; an optical sensor coupled to the pressure resistant structure and configured to detect a signal from the light source; a pressure sensor coupled to the pressure resistant structure, the pressure sensor configured to detect the pressure exerted on the portion of the user in contact with the pressure inducer; and a processor coupled to the optical sensor and the pressure sensor, the processor configured to correlate volumetric data from the optical sensor with pressure data from the pressure sensor and to provide a blood pressure measurement.
